Abstract: A method of improving throughput of a secure digital (SD) bus is described. The method includes accessing, during a data transfer over data lines of the SD bus, read metadata over a command (CMD) line of the SD bus between an SD host and an SD client with a first SD direct command. The method also includes reading a read packet over the data lines of the SD bus from the SD client with a second SD direct command. The method further includes storing the read packet in a host buffer allocated according to the read metadata.
